  The SAP error message CNV_20800001 indicates that there is a format error related to a customer record. Specifically, it states that the customer identifier (or name) exceeds the maximum allowed character limit. The message typically follows this format:
  
  Customer &1: This is the identifier or name of the customer that is causing the error.

  Check Character Limits: Review the character limits for the customer name or identifier in the SAP system. This can usually be found in the data dictionary or field definitions.

  Adjust Data Mapping: If you are using a data migration tool, check the mapping configuration to ensure that it adheres to the character limits of the target fields.
  
  
  Error Logging: If the error occurs during a batch process, check the logs for additional details about which records are causing the issue. This can help you identify specific entries that need to be corrected.
